I would like to add an additional static email address into this variable above so that it becomes permanent. This way when an email receipt is sent to a customer that filled in the form variable, a second receipt will go to "me@nowhere.com".

Here is the actual line of script...

$info_buffer .= "Email: $FORM{email}\n";

I am not fluent with PERL but see my answer somewhere in this flow:

$FORM{email} = $FORM{email} + ";me@nowhere.com (I used to be an old BASIC programer)
